The embodiment, of my invention illustrated .is;.-desig-ned for use inproducing curved paper tubing suitable: for usedn; forming curved yokesfor arment hangers, primarily ladies garment hangers-or other hangerswherestrutsor cross bars are'notdesired. Such. hangers in which theyokes -a-re' formed of woodor wire have been in. use; but. one of. the:aims of the present invention .isto-proVide-a yoke or hanger member ofthe proper curvature to which a suspending hook may .be easily attached,andformed in its entirety of relatively. inexpensive paper stock .Whichwhen completed is strong and rigid and at the sametime light in weight.Anadditional advantage of a hanger yoke of this character is that. itretains the garments more effectively than. wood or wire, that is,thereis asubstantial resistance .to..the tendency. of. the lightgarments or the supporting straps thereof for sliding oif the hanger.

Inmy Patent 2,203,006. issuedrllunei, 1940, I describe a. method of.forming ,papertubesembody ing certain ofv thesteps. oflmy presentinvention. The method-and apparatus disclosed in that pat ent. isdesigned primarily for the manufacture ofpaper tubes for use. asstrutsingarment hangers. in. whichlthe. yo'ke. .is formed of wire.

A further .feature of. importance in the presj ent invention is that.the. tube forming operation is such that substantially no. "lateral or.longitudinal. stresses; are imposed; on the .materiallor stoc'kduringthe manipulation thereof, into a multi -ply. .web. or. forming thesameinto tubular form. "Thls permitsthe use of a relatively inexpensive.orflow grade o'f'stock without the finished product being objectionablyweak or having weak spots or zones.

Referring; to the accompanying, drawings, I illustrate in Fig. 1 a,machine adapted for the complete forming; of the curved tubes from. aweb of paper. The cutting off" mechanism used whenfit is desired to.divide the tube into sections suitable. for garment hangers illustratedis not shown, While th machine. illustrated is highly desirable forpracticing my method, 1 recognize that my method may be practiced by agreat variety of apparatus.

In the embodiment illustrated the main frame I is provided with asuperstructure 2 including a laterally extending support 3 on which aremounted certain of the operating instrumentalities. The completed curvedtube is indicated by the numeral 4 at the right of Fig. 1, While theframe 5 serves as a support for the web of paper stock 6 at the frontend of the machine. The apparatus is driven from a motor 1 throughvarious operating connections which are not described as the inventionis not limited or directed to such details of construction.

In Figs. 2A, 2B and I illustrate diagrammatically the entire procedurein accordance with the method of my invention. The web 6 is led from thesupply roll over a suitable idler 8 and past a slitting couple generallyindicated 9, whereby the web is subdivided longitudinally into parallelportions 6|, 62, as illustrated in Fig. 5. Following said subdivisionthe webs 6| 62 pass through a pair of driving rollers generallydesignated l0, thence upwardly over an idler and between a gluing rollerl2 and a coacting support roller I3, the gluing roller engaging with asupply roller l4 mounted in a suitable tank I5 and being disposedbeneath the advancing webs GI, 62. Roller l2 applies adhesive 63 to thewebs 6|, 62 in parallel bands as illustrated in Fig. 5. This adhesive isof a quick drying nature and the paper is preferably of such an openfibered character that a substantial penetration of the adhesive takesplace in addition to the surface coating for adhering webs 6|, 62 to oneanother and so as to enhance the stiffness of the completed article whendry. It will be noted that the wider of the two parallel webs has alongitudinal border portion 64 left free from the application ofadhesive.

Following gluing of the webs, the same are superposed on one another inthe manner illustrated in Fig. 5, this operation being performed bypassing the web 6| rearwardly around an" idler |5 which is canted at anangle to the horizontal and serves to direct web 6| onto the web 62 atthe glued portion thereof, two corresponding edges of the superposedwebs being flush with one another following said overlapping.

The superposed Webs next traverse a scoring couple I! comprising rollershaving coacting male and female scoring members adapted to impart thespaced parallel score lines 65 to the superposed webs, as illustrated inFigs. 5 and 6,

thus preparing the same for folding during the further longitudinaladvance of the webs. One of the score lines is disposed substantiallymedially of the overlapped superposed webs, while the other falls alongthe edge of the top web 6|. order to prevent undue gumming and cloggingof the scoring roll which engages the glued side of the web I provide asuitable wiper l8 which, like the scoring couple, is suitably mounted onthe superstructure 2. lation and hardening of the glue solution on thescoring roller.

Following scoring, the web passes to a folding way comprising aplurality of folding arms I9 acting to direct the various parallelportions of the scored web into folded relation in the manner clearlyillustrated in Fig. 7. The web emerges from the folding way in therelatively flat section illustrated in Fig. 8 and next enters the bightof a pair of driven coacting male and female form This wiper preventsaccumu rollers 20, 2|, respectively, whereby the multiply folded stripresulting from the operation of the folding Way is given an initialconformation toward its ultimate tubular outline by bending the edgesthereof downwardly as shown in Fig. 9. The form rollers 20, 2| at thesame time serve to advance the web through the subsequent successivelyacting concave forming roller pairs 22, 23, 24, it being appreciatedthat the two rollers of each of these pairs are respectively identicaland act on the sides of the initially conformed web issuing from rollers20, 2| to progressively bend the same in the manner illustrated in Figs.10, 11, and 12 until the opposite edges of the multi-ply strip arebrought into abutting relation, as illustrated in Fig. 12, leaving theunglued longitudinal portion 64 on one edge to overlap the other edgeexternally of the tube. During passage through the pairs 22, 23, 24 thisoverlapping portion 64 has adhesive applied thereto by means of asuitable applicator 25 supplied from a tank 26. The tube then passesthrough a series of coacting concave roller pairs generally designated27 by which the overlapping glued flap is pressed onto the exterior ofthe opposite abutting edge and firmly adhered thereto to hold theadvancing stock in its tubular form.

The various successively acting web folding and tube forming or rollinginstrumentalities referred to above are appropriately mounted in anysuitable manner on the laterally extending support 3 of thesuperstructure 2, as illustrated in Fig. 1. The particular rollermountings employed have not been illustrated in detail, since they formno part of the present invention; however, appropriate provisions tothis end will readily suggest themselves to those skilled in the art.

As the stock in its completed form issues from the finish roller pairs21, it enters a bending and setting device which is generally designated28 in Fig. 1. This device comprises a suitable bracket-like support inthe form of a pair of spaced plates 29 secured in an appropriate mannerto the support 3 and extending rearwardly beyond the same anddownwardly. One of the plates 29 has rotatably mounted thereon thealternate pairs of horizontally and vertically journaled coactingconcave surfaced bending and setting rollers 30, 3|, respectively, thesepairs being successively arranged in the outline of an arc. The foremostof the horizontally journaled pairs, specially indicated by thereference numeral 3|J| in Figs. 1 and 13, has the lower roller thereofmounted on a shaft 302 provided with a gear 363 indicated in dottedlines in Fig. 13. This gear is driven by a suitabl meshing driver 304also shown in dotted lines in Fig. 13, to advance the formed tubethrough the bendingsetting device in a positive manner.

The next successive pair of horizontally journaled bending and settingrollers, particularly designated by the reference numeral 365 in Fig.13, is provided with diametrically spaced embossing projections 306 inthe concave surface of the lower roller'30l of the pair, whichprojections are operable on the tube as it passes between this couple toform spaced indentations 308 in the bottom side thereof and therebyfacilitate bending of the tube to curvilinear outline. Roller 301 isprovided with a driving gear 309'in mesh with idler 304 and theremainder of the horizontally journaled pairs are also provided withappropriate driving gears (not shown), suitable idlers likewise notshown being employed to drivingly connect these gears. The driving and'idler gears are all preferably mounted in the space between plates 29.

Disposed beneath the initial pairs of bending and setting couples 39, 3iis a gas burner 32 or other suitable heating or drying device, theburner being supplied with heating medium through a connection 32'whereby in passing through the setting roller the tube is heatedsomewhat so as to expedite drying and setting of the adhesiveimpregnating the same and holding the tube in desired outline.

As stated, the successive pairs or couples 3!), 3| are arranged inarcuate disposition, as clearly illustrated inFigs. 1 and 2, with theresult that the tube is given a permanent set in curvilinear outline asit passes through these couples and is indented, bent and set by dryingin the device 28. This curvilinear outline is maintained by means offurther spaced and opposed concave idlers 33 mounted on an arcuateextension 34 secured to support 29, the said idlers 33 being disposedalternately on opposite sides of the curved tube to guide the same in ahelical path to its point of discharge in the finished form indicated bythe reference numeral 4 in Fig. 1. At this point the tube is cut inappropriate lengths of from to 17 inches. The radius of curvature of thetube contemplated by the invention is-approximately 36 inches and thearc in which the bending roller pairs 30, 34 are disposed is arrangedaccordingly.

It should be noted that the tube is curved with the joint on the concaveside of the tube, and that the spaced indentations in the tube extendtransversely across the joint. This greatly facilitates the curving stepand the curving step does not tend to open up the joint; in fact, thereis a tendency to close therjoint or urge the abutting edges toward eachother. While with the transverse scoring or indenting the tube may bebent with the joint otherwise" positioned, this positioning of the jointon the concaved side of the tube is very desirable as a step ofmanufacture. The'tube is thus conformed to the desired curvature priorto the setting of the adhesive and is maintained in this curvature untilthe adhesive is substantially set, when the tube becomes rigid and doesnot tend to distort or straighten. Using the multi-plies adhesivelysecured together provides a structurein which the adhesive, serving notonly to bind the parts .together but as a stiffening agent, is quiteuniformly distributed throughout. The result is a rigid structure and astructure which is very economical to produce, both in material andlabor factors.

Following production of the tube lengths or yokes in the mannerdescribed, the latter are pinched or compressed at the ends 35 thereofand the suspending hanger 36 is attached in any suitable fashion toprovide the finished garment hanger. This is an extremely light andinexpensive article well adapted for supporting ladies garments,inasmuch as the material thereof permits the pinning of garmentsthereto. The hanger is amply strong for its intended purposes by reasonof the folded multi-ply and rolled tubular construction, impregnatedwith adhesive which strongly resists bending or collapse.

It will be evident that the indenting of the bottom of the tube in themanner described while forwarding and setting the same greatlyfacilitates the bending and setting thereof in its desired curvilinearoutline.

-I have illustrated and described my improvements in anembodimentwhich'is very practical.

I have not attempted to illustrate or describe other embodimentsoradaptations as it is believed this disclosure will enable those skilledin the art to embody or adapt the invention as may be desired.
